Works well, it’s a bit finicky and needs a lot of adjustments to get it right, even then it still beeps on the up stroke sometimes. Definitely gives you a piece of mind knowing I’m not under or over charged.

So much easier to use than the Dillon powder checker and more accurate and less expensive. I use this on my Super 1050 with an AmmoBot drive system. This is an absolute necessity for auto driven presses.

Precise enough to avoid empty/low charge or double charge pistol cartrigdes with fast powders.

Nice product, easy to install does what it has to do

Great product! Switching from the Hornady powder cop die to this. Used it on a Hornady LNL to load 9mm and soon to be used with 223. Station 1 resize then prime, station 2 powder drop, station 3 DAA Powder Check, station 4 Hornady bullet feed and station 5 seat and crimp. I wouldn’t use a bullet feed die unless there was a powder checker and with the audible alarm you don’t have to watch a rod go up allowing you to use your eyes else where.

I mounted the DAA magnetic powder check onto my Dillon XL 650. The fine tuning took some time but once its set, its very reliable. However there is a downside to the tool: When a fine flake based propellent is used, some of the flakes tend to stick to the rod en subsequently fall off resulting in the shell plate being covered with powder after a while and the brass filled with an inaccurate amount of powder...

[DAA Reply]: As of Sep 1st 2021, the plunger tip is made out of brass which should solve issue.
